My drivers seat now shift a bit when turning or breaking, sometime during acceleration. Seems to shift a bit (maybe a mm or two) on the right side. It's not happening where it bolts to the rails, it's above that.

Has anyone had it and been able to resolve it?

 

Mine seems a little loose too and makes a single pop sound when I get in. I've just had the car 2 months so I'm still getting to know it.

 

Should be solid....
sounds like something is broken...
maybe the frame is fatigued? You might be able to disassemble the seat, weld it...BUT...
Maybe a upgrade to a gen2 front seats (there a a few diy's) with less miles will be the simplest fix...so many gen2 are paerted out due to engine issues...
You can sometimes get gen1 seats out of a gen1 CVT that match, but the foam is still going to be hitting 10 years old...so the gen2's fit and work fine with minimal changes...are newer...and most say they are more comfortable.

 

I've found that the seat's height adjustment gets some play in it over the years.
I had it fixed under warranty when the car was only a few years old. I'm
trying to remember if they replaced the rail or the lower seat frame - I think
it was the rail. It's returning gradually, but I just keep the seat at full height
which keeps it from shifting. Only happened on the driver's side, probably
because I drive alone so much of the time.

My Gen1 has this bizarre behavior where I can adjust the seat and have it feel solid in every direction for twenty minutes of driving.... then I'll pull to a stop and feel it move and "click" into a different position. Once this has happened, it will be fine until I adjust it again.

Someone, perhaps on this forum, took the seat fore/aft adjusters apart and discovered some subtle issue. The fix was more trouble than I wanted to deal with, but I do recall the problem was something very weird and unusual.

yup, mine does exactly the same thing.

Mine isn't shifting into a new position. It appears that the problem is the rivets in the frame. mechanic said I need a new frame. Parts and labor about $900+.

So now I'm looking for a used replacement seat......

 

A new bottom frame looks like this. Play in the seat height adjust are control with this unit.

For problems with rail tracks. ( Forwards and reverse ) make sure your seat rails are parallel and the the distance from the front rails to the rear is the same. It one rail is damaged of more forward/ back then the other rail, then you will lock the seat into place on one side , then when you hit the brakes you get that click with the seats flexing and locking on the other side with the weight of the driver.

Yeah, I've also been having this issue with my driver's seat in my 2006 R53 for approximately a year and a half. I hasn't worsened, but it's definitely become an annoyance. Thanks for sharing your findings; now I have a idea as to what to look for when I check it out to see if I can repair it myself.

 

Yea my 05 does this I kinda ignore it

 

Anyone ever figure out a solution to this problem?

I have same issue in a 2005 R53

 

Mine does this too, but only once in a blue moon.
